| 제목 | Structure and Activity of NiCo-Layered Double Hydroxide (LDH) Catalysts for Alkaline Oxygen Evolution Reaction |
| 초록 | The NiCo layered double hydroxide (LDH) catalystswere electrodeposited on a carbon paper with various Ni:Co ratios (100/0, 99/2,90/10, 50/50, 40/60, 20/80, 10/90, and 0/100) and applied for the alkalineoxygen evolution reaction (OER). The X-ray absorption near edge structure (XANES)spectroscopy was measured to characterize the structural properties of the NiCoLDH before and after the OER, which revealed that the phase stability ofNiCo-LDH was significantly enhanced with the addition of Co more than 10%. Moreover,the OER performance of the catalysts at 10 mA/cm2 followed theorder: Ni20Co80(0.66V) > Co100(0.69) > Ni100(0.71). These resultsdemonstrated the beneficial impact of Co in the NiCo-LDH for the alkaline OER. |
